PC FPS Drops After Certain Time

[oxiclean]

As of a month or two, maybe a little bit longer my FPS in games drops from like 40 and above (depending on the game) to about 10-17 fps. Now my FPS doesn't drop if I start up my computer and launch a game and start playing within like 2 to 5 minutes from windows startup. However if I don't launch whatever game I am planning on playing for like 20 or 30 minutes after windows startup then once I am on the game the FPS is very low. I have no clue as to why this is, but here are some steps I have taken to try and eliminate certain possibilities.

 

1.) Uninstalled my GPU drivers via Display Driver Uninstaller and re-installed them via the Nvidia website. Didn't Work

2.) Went back to an old restore point (one that I believe was before this issue started occurring). Didn't Work

3.) Tried disabling my anti-virus and firewall to see if those somehow had anything to do with it. Didn't Work

 

As you can see, nothing I have tried so far has worked so I'm starting to think that there's a possibility that this might be a hardware related problem. I will list my specs down below, any help will be highly appreciated.

 

GPU: Nvidia GTX 580 1.5GB running driver version 373.06 (overclocked to 825 MHz core clock and 2025 MHz memory clock. Core Voltage at 1100 mV)

CPU: Intel i7-2600 @ 3.4 GHz (set it in my bios so that it can reach a max of 4.2 GHz when turbo boost kicks in rather than 3.8 GHz)

RAM: Corsair Vengeance 16GB (2x8GB) DDR3 1600 (PC3 12800)

PSU: Thermaltake Toughpower Grand TPG-1050M 1050 Watt 80 Plus Gold

Motherboard: ASUS P8Z68-V PRO/GEN3 running BIOS version 3802

Hard drives: Kingston 240GB SSD (operating system & few games), 2 500GB HDD @ 7200 RPM (one has pagefile only and the other has my programs, music, etc).

Operating System: Windows 10 Pro 64-bit

What are your temperatures?

[oxiclean]

GPU idles at around 40-45 degrees Celsius and under load it operates at anywhere from 60-80 degrees Celsius.

 

CPU idles at around 38-42 degrees Celsius and under load it operates at anywhere from 50-70 degrees Celsius.

sounds like an unstable oc leading to it  being locked at 2d clocks. try running gpu-z and check it once you get the fps drops. if the freq refuses to go higher than ~405, then it means your oc is unstable and you have to lower it

Your CPU is throttling from heat. That CPU should be around 38-40c on idle not 50c. They don't like going into the 70s. I recall people being able to run them overclocked at hit 60c and your CPU is at stock speeds. You need to fiddle with mobo settings as I was having issues like you. It was slightly different but all of the sudden my OC of years was not stable.... Rendering Video would render the computer slow because of thermal throttling. However... it had nothing to do with the CPU itself. Some mobo setting was not liking it anymore... still not sure what... but I reset everything to normal... and then I could OC again perfectly fine... was a strange thing.  My games however were fine.

afaik tjmax on sandy bridge is 90C, so it should not be thermal throttling. its more likely an oc issue

my r9 390 used to go into the 90s and worked fine

Looks like the freq isn't going higher than 50.6 MHz. I'm going to return my card to stock settings and see if that solves the issue, I'll get back to you guys on it.

[oxiclean]

Returned the card to stock settings which are 1000 mV core voltage, 772 MHz core clock, and 2004 MHz memory clock. Still ended up with the same result, card not going past the 50.6 MHz core clock mark on GPU-Z when the game is open. Any ideas guys/girls?

[alphaproject]

50.6 core clock...weird indeed.

Here's an image of what GPU-Z looks like when everything is running good versus when it's running poorly (50.6 MHz). Note that on the left image which is GPU-Z running as it should my graphics card is running at maximum speed and the GPU Load is @ 99 percent, not 1 percent. It's just showing like that because of me alt and tabbing to take the picture. Also note for the image on the right hand side the GPU Load is @ 100 percent apparently, or at least according to GPU-Z it is. Showing as 7 percent because of me alt and tabbing out the game to take the picture.
